Added "advsearch.get.html.ftl" in path "/src/main/resources/alfresco/web-extension/site-webscripts/org/alfresco/components/search/". You can see that I override the default template adding the two reset buttons (clear-button-1 and clear-button-2). Maybe it's possible to do it in a cleaner way and don't override the default template. But I couldn't do it in another way...:
